i have a 5.3 in my jeep with a turbo 350 behind it. The original iac took a dump so i installed a new one now when i crank up it idles to 2500 for a few seconds then starts coming down to 700 or so after warm up. My old iac would not rev the motor that high. Can i adjust the iac motor by turning out the end or turning it in. i understand that it is a worm gear i just feel like it is out of wack some how. I have the throttle blade closed all the way with the stock hole in the TB. I dont know if i need to turn the throttle stop out more to give it a tad more air? Thanks in advance for the help.
